Question

(2x-9)/15-(x+2)/6 = (2x+15)/10 - (3x+4)/5 - 1/6 am nevoie urgent

Answer 1

Răspuns:

X = 25.5

Explicație pas cu pas:

(2x-9)/15-(x+2)/6 = (2x+15)/10 - (3x+4)/5 - 1/6

2x/15 – 9/15 – x/9 - 2/6 = 2x/10 + 15/10 - 3x/5 - 4/5 -1/6

2x/15 – x/9 – 2x/10 + 3x/5 = 15/10 - 4/5 -1/6 + 9/15 + 2/6

2x/15 – x/9 – x/5 + 3x/5 = 3/5 - 4/5 -1/6 + 3/5 + 1/3

(6x – 5x – 9x + 9x) / 45 = (18 – 24 – 5 + 18 + 10) / 30

X / 45 = 17 / 30

X = 45 * 17 / 30

X = 25.5
